Supercast SWX

Description

Supercast SWX is a gun applied, grey, elastomeric waterswellable paste. The hydrophilic properties of Supercast SWX display good consistency in swell rate during repeated wet/dry cycling. Expansion of the product on contact with water creates a positive pressure against the faces of the concrete joint, thus preventing the passage of water

Uses

Supercast SWX can be used as an adhesive for bonding Supercast SW strips or as a problem-solving hydrophilic waterstop in difficult access areas including:

■ Sealing around joints in precast manhole covers, cable ducts and pipes, etc.

■ Sealing around precast segments

■ Sealing between rough surfaces, e.g. slurry walls and concrete slabs

■ Sealing around H-beams and other penetrations through concrete structures

■ Sealingaroundconventionalrubberandplasticwaterstops to provide ‘belt and braces’ seal prior to concrete pour

Advantages

■ Fast curing: Enables early concrete pour and rapid return to service. Allows hand-applied concrete cover within 2 hours on emergency repairs and large-scale concrete pour after 8 hours

■ Excellent seal on rough concrete: Gives improved water tightness. Plugs inequalities in rough concrete to produce a tight seal

■ Excellent adhesion: Quick and easy to apply to a variety of uneven joint surfaces remaining firmly in place during concrete pour

■ Water swellable: Expands by 200% producing a watertight compression seal

■ Durable: Excellent wet/dry cycling retaining elastomeric character and swelling performance due to high tolerance of the cementitious environment
